Use of Natural Light

The Venice setting was outstanding but beyond that what helped really make this film for me the way Roeg captured the natural light and used it to set the mood. That late afternoon autumn sunlight, not too bright and a bit reddish, when it's cold enough to see your breath without being freezing, he caught it just perfectly a number of times - in the cafe, outside the church, on the canal - and really took me there. And it is sort of a film set in the dusk, with murky powers at work, the unnatural forces and danger never really made clear until the end and not entirely even then. It is a big gamble because if you don't put it together near perfectly then you little to fall back on, people will say you made a dumb film with a weak little plot, but for me he pulled it off.
